MRP Rescheduling

Hello all,
Can you please tell me what rescheduling is? On what criteria is rescheduling carried out by MRP?
Also, the column rescheduling date in MD04, can you please let me know how and why this is calculated?
Thanks and regards,
Deepthi.

Hi deepthi
An important group of the exception messages mentioned above are the rescheduling proposals. In the net requirements calculation, the system checks whether warehouse stock or firmed receipts are available in sufficient quantity to cover requirements. If a material shortage exists, the system usually creates a new procurement proposal. The rescheduling check is used to change the dates of already existing firmed receipts not planned on the same day as the requirement to suit the requirement date. For this purpose, the system displays the appropriate exception messages with rescheduling proposals for these firmed receipts to be processed by the MRP controller.
You have defined the rescheduling parameters in Customizing for MRP:
per plant in the IMG activity Carry out overall maintenance of plant parameters
per MRP group in the IMG activity Carry out overall maintenance of MRP groups
The rescheduling date is only displayed in the MRP list. The system only displays the current stock/requirements list if you trigger rescheduling with the appropriate function.

MRP Reschedules PO ahead of Scheduling Agreement

Hi,
We have a situation where one company code (Company A) buys product from a second (Company B) via an inter-company Scheduling Agreement. The schedule lines are generated automatically from MRP.
Company A now has a need to purchase a one-off quantity of the same product from an external company and so have subsequently raised a Purchase Order with delivery dates in the future (after the next requirement from company B is due).
The result of the MRP run has been to prompt rescheduling of the Purchase Order in to meet immediate requirements and only generate schedule lines from Company B after the full Purchase Order quantity has been used. This is not as required, as the dates on the PO are those that are achievable by the external supplier.
I can't find any settings that relate to a prioritising of MRP elements which would imply that a PO has precedence over a Schedule Line, and I would rather not fix the schedule lines of the Scheduling Agreement.
Has anyone seen this before, or knows what I'm missing.
Thanks

Hi suresh
The requirement goes this way.the sales person creates a scheduling agreement instead of a sale order.The next process is running MRP for the scheduling agreement .
Just he wants to know through a report what are the sceduling agreements peding for MRP run.

MRP Rescheduling messages with planning calendars

Hi Experts,
I have successfully set up a planning calendar and applied in material master with a period lot size so that MRP creates purchase reqs with a delivery date on a specific day of the week.
My problem is with the rescheduling dates that appear in MD04 for firmed receipts. These rescheduling dates align to the requirement date date and do not take into account the planning calendar.
Do you know if it is possible to configure the rescheduling to take the planning calendars into account?

Hi Timonthy,
I just had a similar problem last week and the simple answer was to remove the re-order point.
Then it orders only on the day it should (unless you again go below safety stock) up to the forecasted amount.
The other option is to maintain a delivery schedule as well.
That way it will always schedule the delivery on the day you want even when it plans on a day you don't want.
While SAP is not very consistent on what they call the two schedules, the one that is required for MRP is the planning calendar (order cycle) and the optional one is the delivery calendar. Delivery dates are moved to match the delivery calendar regardless of lead time.
Not too sure whether that helps, but it solved my problem.

Charl

MRP-Rescheduling Horizon

Hi Experts,
Could u please, explain what is Rescheduling horizon (OMDQ)?
In OMDQ , if I change planning horizon to 999 days from 100 days.What will be the effects of it?
Thanks in advance
Regards,
jay

Dear,
The rescheduling horizon is the period in which the SAP System checks whether the existing dates still suit the requirements situation for receipt elements that can no longer be automatically changed in the planning run. If the dates of a particular element are no longer suitable, the following exception messages are created depending on the requirements situation.
Rescheduling check is to change the dates of already existing firmed receipts which were not planned on the same day as the requirements day to suit the requirement.
For this we need to define a rescheduling horizon.
Rescheduling horizon defines the period for bringing the receipts that should be taken into account for rescheduling.
For further info: Please visit: http://help.sap.com/saphelp_40b/helpdata/pt/b4/7055967935d1118b3f0060b03ca329/content.htm
For second question, if you change it to 100 days,
If you put 100 days, for net requirement calculation, system will consider the firmed planned orders & receipts within 100 days.
If one firmed planned order is in 4 months before ie 120 days before, system will not consider for net req calculation.
Say demand is 100 on 23.09.08
Resheduling Horizon 100 days
Firmed planned order in 23.04.08
When MRP run system create planned order for 100 qty.
If rescheduling horizon 999 days, system will not create planned order & system propose reschedule the firm planned order to 23.09.08

MRP Rescheduling Error with quota arrangement

Hi i have a problem when using a Quota arrangement in MRP. When i use NME59N to order,the system proposes to bring the first vendor 100% for a month and then the next supplier for a minimal share the following month. the quota is available clearly in PR'S but when converted to PO'S the rescheduling takes the first po as a referrece instead the assigned PR'S.Can any one help me sorting out this?

When you run ME59N you will convert the requisitions inot POs (the same requisitions that you see in MD04). The vendor assignment is not modified by ME59N. This is already done by the Quota when the MRP runs.
In ME59N you can control if each requisition will be converted into a single PO, if multiple requisitions are going to be joined and converted into a single PO, etc.
I am still not sure if your problem is with ME59N or what you don't like is how the vendor is assigned (considering the Quota) when the MRP is executed? If you see in MD04, is the assignment correct? if the vendor assignment that you see in MD04 is not what you want.. then we should find a solution working with the Quota and with the MRP paramenters. Is your problem the vendor assignment that you see in MD04?

Incorrect Rescheduling in MD04

Hello experts,
I’m having some problems with MRP rescheduling. With this situation:
If I launch MRP,instead of having a 10 message for the purchase order, it generates a new purchase requisition and indicates that I should cancel the PO (Error 20):
I have been changing the consumption mode, but it does not work.
Is possible to have this behavior??
Regards

Hello
The purchase order is probably outside the rescheduling check or it is not included on rescheduling on your customizing.
You can check the value defined for the rescheduling horizon and if the PO is included on the rescheduling check on OMDW.
Take a look on the following note where the recheduling check and the customizing is explained in detail:
What is rescheduling and how does it work - ERP Manufacturing (PP) - SCN Wiki
Also take a look on the following document for the frequent issues on MD04:

Experiencing "timed out" error when uploading podcast

I am experiencing a "timed out" error when uploading a podcast to iTunes. Using PC. I've updated iTunes...

- You really need to ask the Basis team to extend the maximum run time for background processes (30 mins is too short).
- You can also try to reduce the run time by setting up BOM Buffering in configuration so if the same BOM is used again and again (in your case of delete and recreate planned order, yes), it will read from memory.
- You should set the planning horizon and use NETPL (net change in planning horizon) in daily run. So that the run will only find the relevant changes in order proposal up to certain days, thus reduce run time.
- You should discuss with your BASIS team about the list of background job in the batch windows. Specify time in such a way that the performance-critical job (i.e., MRP, reschedule sales order, certain customized report, etc.) doesn't run at the same time.
- You can increase the number of parallel processes to issue several jobs to run MRP at the same time.

MD04--- Delivery date--***URGENT***

Hello Gurus,
In md04 the delivery date is pushed out to open sales order date and i see exception 15
What setting in the system makes it look for dependent requirements
WE WANT delivery date as per PLANNED LEAD TIME
Can any one help me get through this
Will award full points
Justin

what is checking group 32 what is And planned delivery date is 95
I am not getting you.
If there is no commited date in the PO, that means available qty is zero?
Why are you using STO, you told it is PO?
If I correct- you create a sales order, then you create PO to get that material
Now in sales order you have availability check activated, hence it will look for the receipt element.
Now you are creating PO manually and entering the delivery date manually...
let us say del date you eneterd today.
Your planned delivery days let us say 20 datys,
the system will say "can delivery date met? - it is warning message. if you stll save syetem will save that order.
Now when you see the date in MD04 and if you run MRP, then if the delivery date us not matching with SO delivery date, then system will give resceduling date, which willnot be copied to PO unless you change it.
See below MD04 sumulation
DATE---recp/issue-resch date-qty--balance
20.11.2007Stock--
0
10.12.2007SO--
-10 -
-10
15.12.2007PO10.12.2007-- 10 -
0
Since as per the date proposed by system as per MRP2 view data(planned del days) is 15.12.2007. But required del date from SO is 10.12.2007, hence MRP reschedules and give youn indication that del date should be 10.12.2007 instead of 15.12.2007.
Is it the case with you? if not please give example like what i gave above.

Masss Scheduling of Planned Order

Hi
Is there is any transaction for Mass Scheduling of Planned orders preferabaly at plant level.?

Dear Mayuresh,
In my understanding there is no T Code to schedule as set of planned orders
This will impact on the other reciepts and only during MRP rescheduling happens.
But also have a check the FM that Mr.Brahmankar has suggested.
Dear Rupesh,
Do u think even if you have an action plan and execute MDAC will it help to schedule the planned
orders?

MRP Type V1 - Does it create Exception Message for "Reschedule-in"?

Hello Experts,
We are using MRP Type V1 (Which has the Manual Re-Order Planning + External Requirements). However we are facing and issue with the Rescheduling part. Scenario is as following:
Material ROP is - 5000
Open Pur Ord is - 5000 (due in 01 June'09) based on the Std Lead time of the Material
Stok on hand is - 0
At this point a Sales Order is entered for 1000 pcs
After MRP Run, we expect an Exception Message for the Purchase Order to have "Reschedule-in". But, instead, system creates a PReq for 1000 pcs and the required date is NOT the Sales Order required Date but based on the Std Lead Time of the Material.
I have set the Material Lead time - 60 Days
I have set the Reschedule horizon - 0 Days ( I even tried with different Days but NO use)
However, when I change the MRP Type to PD, system generates a "Reschedule-in" Exception Message for the Purchase Order.
How can I get the "Reschedule-in" Exception Message for the Purchase Order with the MRP Type V1?
Thanks for your help in Advance!

Anil,
Reorder point/External MRP performs net requirements calculation (within replenishment lead time). If the existing firmed supply elements minus the existing requirements bring the projected stock below ROP, it will propose an order that will bring the projected stock back to reorder point. The proposal will generally come at replenishment lead time.
In the normal business cycle, your sales order would confirm to lead time, and you now have a confirmed sales requirement at lead time, plus a new purchase req to bring the stock back to the reorder point. The scenario you have described is working exactly as it is designed. Consumption based MRP will not normally try to reschedule supply elements to match requirements inside of lead time.
Rescheduling horizon generally is counted from the end of lead time. It won't help you here.
I guess if you insist on having a reschedule message, you could change your lead time to 0 days. Not a wise move in my opinion. You then have locked yourself in your choices of types of Sales order availability checks into one that ignores lead time. You also have to find a way to let your buyers/planners know what the 'real' lead time is when they place their orders on the vendors.
I don't know why you are using a consumption-based planning type (reorder point). It sounds like your business requirements are that you actually need to be using a demand-type planning method (eg, your supply elements are driven by your demand, not by a reorder point/desired stock level). If PD works the way you want, why aren't you using it?

Mass Reschedule of Purchase Orders - from MRP

We are using MRP (not ASCP). Is it possible to perform a mass reschedule of purchase orders (note, not purch reqs, but purchase orders), directly from the planner's workbench? I think it is not possible with MRP, but ASCP seems to have the functionality. Am I right? Has anyone got any workarounds or tips on how to mass reschedule given that MRP can't do it?
Thanks

You were also correct that ASCP does have that feature. You can reschedule the "need by date" of existing purchase orders from the ASCP planners workbench. You can query purchase orders by specific attributes (like category or supplier) and then adjust the dates and release these changes to purchasing.
MRP does not have the ability to reschedule existing purchase orders.

Kevin

Rescheduling at material level or MRP controller level

Hi,
I have come across one scenario:MRP need date and PO delivery date are within one week no exception message will be generated.
We can acheive this by maintaining tolerance values in OPPQ/OMDW. But problem is user wants this functionlity for purchased parts only and not for Inhouse mfg. parts.
As per my knowledge if we maintain tolerance values in OPPQ and select all recipts elements these values are applicable for those one also.
To overcome this issue is there any standard config exist in SAP? or else please let me know any enhancement to resolve this issue
Thanks in advance for your valuable input
Regards,
Alex

Hi
Thanks a lot for your quick reply
Let me clear you this issue
User wants rescheduling tolerance values in OMDW. But there requirement is it should affect only for purchased parts and not inhouse parts. For inhouse parts they don't want to consider these tolerance values. Creation of MRP group is out of question in this business.
As I know if we maintian tolerance values in OMDW it will affects for all receipt elements. So my question is: Is there any enhancement available in SAP where we can apply this tolerance values for procurement type 'F' materials only. (Externally)

Alex

Reschedule Exception message in MRP

Hi ALL.
MRP suggests rescheduling a PO to create a new one for delivery in the past. The planner clicks the Processing Indicator (Dealt With). As soon as additional orders come in and change the quantity, the "Dealt with is over-ridden" Can this be prevented? Suppress "Reschedule" exception messages?
Please Advice,

Not to reschedule in the MRP run.

Hello!
I have product   P000GR00000000 consisting a
component say B000GR00000000 .
               If i create production order of P000GR00000000 for DATED 30.09.2007 of 100 EA.then order will reserved -100EA for B000GR00000000 & when i take MRP run it will generare plan order of 100 EA for B000GR00000000.Similarly if i create production order for P000GR00000000 for dated 30.10.2007 of 200EA.Then MRP run will generate 200EA plan order for B000GR00000000.
      Now, i create production order for P000GR00000000 of 300 EA for dated 30.11.2007 & meanwhile the production order of P000GR00000000 DATED 30.09.2007 is technically completed then order reserved for B000GR00000000 of -100EA will be cancelled.If i take MRP run now ,then order reserved of -300 EA for B000GR00000000 will rescheduled,that i want to restrict.
   Is there any solution Not to reschedule in the MRP run if order is TECO.
please give the solution.
regards,
mangesh

Hi Mangesh
You can define Rescheduling at plant level or MRP group level using OPPQ/ OPPR or OMDW. if you define at plant level then no need to create in MRP group and assign to material
secodly if you want to avaoid the Reschedule Exceptions then
You can define tolerance values in additon to Resheduling horizon. for the creation of exception messages, in Customizing. These values define a time period in which no exception message is to be created, despite the fact that a rescheduling proposal may exist.
If you don't want reschedule check for production orders then you can remove the flag against production orders in the firmed elements.
if you TECO the order Normally MRP should not consider while planning!
please check onesecond and come back
But Teco will allow you for posting (GR/GI)
hope this helps
